  # Python Arithmetic Operators Example

Show

Assume variable a holds 10 and variable b holds 20, then

OperatorDescriptionExample
+ AdditionAdds values on either side of the operator.a + b = 30
- SubtractionSubtracts the right-hand operand from the left-hand operand.a â€“ b = -10
* MultiplicationMultiplies values on either side of the operatora * b = 200
/ DivisionDivides left-hand operand by right-hand operandb / a = 2
% ModulusDivides left-hand operand by right-hand operand and return the remainderb % a = 0
** ExponentPerforms exponential (power) calculation on operatorsa**b =10 to the power 20
//Floor Division - The division of operands where the result is the quotient in which the digits after the decimal point are removed. But if one of the operands is negative, the result is floored, i.e., rounded away from zero (towards negative infinity) -9//2 = 4 and 9.0//2.0 = 4.0, -11//3 = -4, -11.0//3 = -4.0

Example

Assume variable a holds 21 and variable b holds 10, then -

```#!/usr/bin/python

a = 21
b = 10
c = 0

c = a + b
print "Line 1 - Value of c is ", c

c = a - b
print "Line 2 - Value of c is ", c

c = a * b
print "Line 3 - Value of c is ", c

c = a / b
print "Line 4 - Value of c is ", c

c = a % b
print "Line 5 - Value of c is ", c

a = 2
b = 3
c = a**b
print "Line 6 - Value of c is ", c

a = 10
b = 5
c = a//b
print "Line 7 - Value of c is ", c```

When you execute the above program, it produces the following result:

```Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
Line 6 - Value of c is 8
Line 7 - Value of c is 2```
